In addition, built into the HDMI 1.3 specification is the technical foundation that will let future versions of HDMI reach significantly higher speeds.
if a cable states to be ver 1.3 it might be wise to go for that one , BUT it may be years before the full bandwith is used.
you have to decide if its a marketing ploy OR its like USB cables on a PC
Some Sony dvd players advertise Deep colour support but fall short of saying its hdmi 1.3, possibly for royalties to HDMI ? Or it doesnt meet the spec ?”

I doubt if Sony are worried about royalties - they're founder members of HDMI. Stating that something is "HDMI 1.3" doesn't actually mean anything, since not all features are mandatory. Stating that a device supports Deep Colour is potentially more useful and will still be relevant if/when an HDMI 1.4/1.5/2.0 specification comes out.
Devices should always work to the lowest common denominator anyway, so a Deep Colour DVD will not use Deep Colour until it finds a Deep Colour-capable display at the other end of the cable.
HDMI cables shouldn't be described as 1.3 - they should be Standard (Category 1) or High Speed (Category 2). This differentiation will still be valid through future versions of the HDMI specification.
